Abstract: Internet of things, big data analysis and machine learning are the troika of the intelligent age, which is of great significance to the intelligent development of science and technology. This paper first analyses the development trend of the backup for disaster recovery, then provides the thinking of "wisdom +" backup system for disaster recovery, on this basis, analys briefly the key technologies of the Internet of things, big data analysis and machine learning, finally uses these techniques to the design of backup system for disaster recovery, and provides a kind of "wisdom+" architecture of backup system for disaster recovery based on the big data analysis and machine learning in the environment of Internet of things, also analys the implementation principle and function of this system.
